\ Be it known that 1, lliun sana'rn, a (-itize of Czecho-Slovakia;residing at Na-" Titr'ona. in the county'of Allegheny and State got lennsylvania, have invented certain new "and useful Improvements in Roof Construcjfjftions for Freight Cars. of which the follo\\ 'fing is a specification. I,

. 1 This invention relates to certain nc-wand] I .16, y

for freighticars and has particular refer- "em-e a freight car'of the usual type en1' bodying a side opening closed by a sliding. door with sections of the roof slidablyjl mounted uponth'e car body capable of being" '7 npiilic'ation filed September useful improvementsEin roof construction moved to present an unobstructed opening at the; upper side of the car for purposes :iof loading the car.

. A further object of the invention has refere'nceto a railroad car designed for the f hauling of freight or the like wherein fixed, cover or roof sections are arranged at oppori site ends of the car while the middle sections of the roof are slidably mounted upon the car body and adapted to be moved to aposition underlying the fixed roof'sections to present an opening at the upper side or roof of the car for purposes of loading the same, cooperating latch devices carried-by the fixed and sliding sections for holding the sliding sections in a locked and closed position.

\Vith the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accom'panymg drawing and claimed.

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevational view of a railway car constructed in accordance w1th the present invention, the sliding roof sections being shown in closed position,

Figure 2 is a top plan view of the same,

Referring m r-e111 detailfto theiacc omf'panying 'dru'\ving there .1 is illustrated a :freight li'anibodyf embodying sidewalls 1, endywaIlsQ and a platform base 3: mounted upon a, standanl construction of wall base. The side walls 1 ofthe canbody areprovided with door openings 4I 'closcd slidf ing doors 5'workingon' runners.fiasclearly slmwnjin Figs. 1 and 2," i

The [roof of the fcarembodies stationary endsections {7 extending inwardlyffromthe end walls 2, each stationaryIend section occupying ap1 )r oximately one quarter of the lengthof theupper side of the car, leaving acentralopen space at the upper side of the JCQLlItlS illustrated, Sliding roof sections 8 opening, each sliding roofsection carrying depending-feet 10 provided lwith rollers 11 resting upon inwardly directed longitudinally extending ledges 12 carried by the inher faces fof the" side walls 1 of the car as clearly shown in Figs. 3 "and 4. The slidin'g roof section 9 has an offset lip 13 overlying the adjacent edge of the sliding section 8 to provide a substantially sealed connection between the sliding sections, the sections 8 and 9 when in closed position lying llz eneagth the cover sections 7 as indicated in 0 hold the sliding roof sections in the closed positions illustrated, a tensioned latch device is carried by the inner end of each stationary roof section 7 and the latch devices including a/ lever 14 pivoted upon the post 15 carried by the roof section 7 and tensioned as at 16 to cause the pin 17 carried by the forward end of the latch lever 14 to be lowered through an opening 18 in the roof section 7 and received in an opening 19 in the outer ends of the sliding roof sections 8 and 9 respectively, the outer ends of the roof sections 8 and 9 being flanged upwardly as at 20, and shown in Fig. 3, for frictional engagement with the lower faces of the roof sections 7 to provide for a substantially rigid mounting of the sliding roof sections 8 and 9.

When it is desired to load the car, the latch "and 9are associated with the upper side of the car and are adapted to close the 1 central levers 14 are operated to release the pins 17 from the sliding roof sections 8 and 9, whereupon the sliding roof sections are slid outwardly adjacent the opposite ends of the car to occupy positions beneath the stationary roof sections-7 thereby presenting an un obstructed opening in the upper side of the car. After loading the car, the sliding roof sections 8 and 9 are moved inwardly with the rollers 11 moving over the ledges 12 to present the lift 13 of the section 9 in a position to overlie the adjacent end of the section 8 with the pins 17 of the tensioned latch devices received in the openings 19 of the sliding sections. In unloading the car the material may be either removed through the top opening or taken from the side door openings 4 by moving the doors 5 upon their sliding mountings 6.

While there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention.

What is claimed as new is 1. A freight car comprising a body having fixed end roof sections and central slidable roof sections mounted on the car body and adapted when in open position to underlie the fixed end roof sections.

2. A freight car comprising a body having fixed end roof sections and central slidable roof sections mounted on the car body and adapted when in open position to underlie the fixed end roof sections, and cooperating devices carried by the fixed and the sliding roof sections for holding the sliding sections in closed position.

3. A freight car comprising a body haw-- ing fixed end roof sections and central slidable roof sections mounted on the car body and adapted when in open position to underlie the fixed end roof sections, a tensioned latch lever carried by the inner end of each fixed roof section adapted to engage the outer end of the adjacent sliding section to hold the sliding sections in closed position.

4. A freight car embod ing a body, fixed end roof sections carrier thereby, an inwardly directed longitudinal ledge carried by each side wall of the body adjacent the upper end thereof, sliding roof sections supported on said ledges with the outer ends underlying the fixed roof sections, and means for holding the sliding roof sections in closed position.

5. A freight car embodying a body, fixed end roof sections carrie thereby, an inwardly directed longitudinal ledge carried by each side wall of the body adjacent the upper end thereof, sliding roof sections supported on said ledges with the outer ends underlying the fixed roof sections, and a tensioned latch device carried by the inner end of each fixed roof section adapted to engage the outer end of the adjacent sliding section for holding the sliding sections in closed position.
